Of the three only 2 is Tajuria deudorix. https://www.inaturalist.org/observations/85070919
In particular it is well to see the black bar in the upper space 3. It is very straight & fully detached.
This observation is also in Kent Ridge Park, indicating a small colony there.
The other two observations have curvatures in both black bars in space 2 & 3.
It may not be a coincidence that all images of T. deudorix are brown, no grey form being seen.
